I will be making a checkerboard cake. I did a search here and elsewhere for recipes. I would like to keep it as simple as possible -- i.e., use 1 yellow cake mix, 1 chocolate cake mix.

Has anyone done it that way, that simply? I've read that sometimes 2 different cake mixes give different batter yields, but I think I'd just use the amount that properly filled the pans.

Also, do you use a non-stick spray on the plastic divider?

Any tips appreciated. I also bought the easiest-to-spread whipped frosting -- 2, just in case. I will have no time for "rework." Thanks!
